Reverse osmosis water purification diagnostic system
First Claim
1. A reverse osmosis water purification unit, comprising:
- a housing which has an inlet port and an outlet port;
a pump that is located within said housing and connected to said inlet port;
a reverse osmosis membrane that is located within said housing and connected to said pump;
a tank that is located within said housing and connected to said reverse osmosis membrane and said outlet port;
a pump monitor that monitors said pump and provides a pump monitor output signal;
a membrane monitor that monitors said reverse osmosis membrane and provides a membrane monitor output signal;
a controller attached to said housing, said controller receiving said pump monitor output signal and said membrane output signal to determine a pump fault condition of said pump and a membrane fault condition of said reverse osmosis membrane, said controller operable to generate a pump output signal when there is the display fault condition and operable to generate a membrane display output signal when there is the membrane fault condition;
an alphanumeric display that is mounted to said housing and connected to said controller and which is operable to display a pump alphanumeric message in response to said pump display output signal and is operable to display a membrane alphanumeric message in response to said membrane display output signal.

Abstract
A monitor for a beverage processing system that can sense a characteristic of the system, compare the characteristic to a threshold value to determine if a component of the system is not operating properly, and transmit the characteristic to a remote site. The monitor includes a controller coupled to a number of sensors that sense various system characteristics such as the water pressure and resistance at various locations of the system. The processor compares the outputs of the sensors with threshold values to determine if the various components are operating properly. The monitor also has a visual display unit which can output the various characteristic values along with processor generated messages that identify a component(s) that is not operating properly or needs preventive maintenance. The monitor transmits data via a modem to a computer located at a remote site. The computer can store and display the characteristics and other processor outputs.
